Clinical trials

The goal of this clinical trial is to learn if cenerimod, on top of regular treatment, works to treat active lupus nephritis in adults with systemic lupus erythematosus and active lupus nephritis. It will also learn about the safety of cenerimod. The main questions it aims to answer are: * Does cenerimod improve kidney function in participants? * What medical problems do participants have when taking cenerimod? Researchers will compare cenerimod to a placebo (a look-alike substance that contains no drug) to see how well cenerimod works when it is added to regular treatment. Participants will: * Take cenerimod or a placebo every day for 76 weeks (approximately 1.5 years), on top of regular treatment. * Visit the clinic every 1 to 3 months for checkups and tests.

The purpose of this study is to evaluate the pharmacokinetics (PK), pharmacodynamics, and tolerability of a single dose of selatogrel in Chinese adults with chronic coronary syndrome. Pharmacokinetics is the study of the absorption and breakdown of the study drug in the body. Pharmacodynamics is the study of the effect of the study drug on the body. Researchers will compare selatogrel to a placebo (a look-alike substance that contains no drug). Participants will stay at the research clinic for 3 or 4 days (2 or 3 nights), during which time they will receive a single dose of selatogrel or placebo. A telephone call for post-trial safety follow-up will be done 30-40 days after the participant leaves the clinic.
